It has a square shape that engages with the notch groove 1 53.

In the mounting structure of the thermistor 30 of the motor according to the present embodiment as described above, first, the main body 3 1 of the thermistor 30 is placed in the mounting grooves 1 18 and 11 of the resin mold portion 10. Place the conductors 3 2 on each side and sandwich the conductors 3 2 between the bulges 1 2 8 and 1 2 respectively.

[0026] At the same time, the notch groove 1 of the leaf spring 15 is formed in the positioning protrusion 14 of the cover 14

5 3 is inserted and the leaf spring 15 is sandwiched between the positioning protrusion 14 and the pressing protrusion 1 4 ₆ so that the notch groove 1 5 3 is pressed against the positioning protrusion 14 and the leaf spring 15 Is easily positioned, held and fixed to the ceiling plate 1 4 3 of the cover 1 4.

[0027] Then, engage the engaging claws 140 of the cover 14 with the bracket 1 of the resin mold portion 10.

When the cover 14 is attached to the bracket 13 so that it is engaged with the engagement hole 1 3 3 of 3, the leaf spring 15 causes the body 3 1 of the thermistor 30 to attach to the resin mold socket 6 10. Groove 1 1 8 1 1 1 Bottom of 1mi

[0028] With this, even if vibration is applied to the motor from various directions, the cover 14 can be securely fixed to the resin mold portion 10, and the thermistor 3 \\0 2020/175 349 7 卩 (: 171? 2020 /006973

The main body 3 1 of 0 can be securely fixed to the mounting grooves 1 1 8 and 1 1 1

[0029] When the thermistor 30 is to be replaced or to be inspected for damage due to damage, the front end side (lower end side in Fig. 2) of the wall plate 14 claw of the cover 14 is moved closer to the wall. When a force is applied to the plate 14 sill, the engaging claw 1 40 of the cover 14 easily disengages from the engaging hole 1 3 3 of the bracket 13 of the resin mold part 10 and the cover 1 4 and the leaf spring. It is easy to remove 15 from the resin mold part 10.

[0030] As a result, the conducting wire 3 2 of the thermistor 30 is removed from between the bulging holes 1 2 8 and 12 of the resin mold portion 10 and the main body 3 1 from the inside of the mounting grooves 1 1 and 1 1. The thermistor 30 can be easily taken out from the resin mold portion 10.

[0031] Therefore, according to the present embodiment, the resin mold portion can be used without using a tool.

Since the thermistor 30 can be easily attached/detached to/from the 10, the thermistor 30 can be easily replaced, maintenance and the like, and the work efficiency can be improved.

[0032] In addition, the leaf spring 15 connects the body 31 of the thermistor 30 with the mounting groove 1 1 of the resin mold 10 and the bottom 1 of the 1 1

1 1 Make the main body 3 1 come into close contact with the inside of the mounting groove 1 1 8 and 1 1 1 by pressing it against ₃ and also engage the engaging claw 1 40 of the force bar _ 1 4 with the bracket 1 Since the cover 14 is pressed against the inner surface of the engaging hole 1 3 3 of 3 to bring the cover 14 into close contact with the bracket 13, the cover 14 is not covered with resin even if vibration is applied to the motor from various directions. Not only can it be securely fixed to the mold part 10, but also the main body 3 1 of the thermistor 30 can be surely fixed to the mounting grooves 1 1 and 1 1 1 1 and the vibration resistance can be improved. You can

[0033] Further, the notch groove 1 53 of the leaf spring 15 is inserted into the positioning protrusion 14 of the cover 14 so that the notch groove 1 5 3 is pressed against the positioning protrusion 1 4. by a this sandwiching the leaf spring 1 5 between the 4 and the retaining protrusions 1 4 _6, easy positioning of the leaf spring 1 5 for the ceiling plate 1 4 3 of the cover 1 4 \\0 2020/175 349 8 卩 (: 171? 2020 /006973

Since it can be held and fixed, even if vibration is applied to the motor from various directions, it is possible to prevent displacement of the leaf springs 15 and improve vibration resistance.

[0034] Also, the bottom surface of the mounting groove 1 1 8 and 1 1 of the resin mold portion 1 0

The length (thickness) 1: between 1 1 and 3 and the connecting line 2 1 8 to 2 1 0 is 3 0 0 to 4 5 0 (3 0 0 £ I £ 4 5 0 ^ ^ 1) Therefore, while exhibiting sufficient insulation performance, it is possible to prevent an increase in heat flux due to the resin during that time, and it is possible to detect the temperature of the connection lines 2 218 to 210 more accurately and quickly. ..

[0035] Note that this embodiment is a thermistor for a running motor used in an electric vehicle.

Although the case where the temperature detecting element is applied to the mounting structure of 30 has been described, the same can be applied to the case where the temperature detecting element is mounted to another rotating electric machine such as an electric motor or a generator.

[0036] Example 2>

Second Embodiment Next, a second embodiment will be described with reference to FIGS. The second embodiment relates to the groove shape of the mounting grooves 11 8 and 11 1. In the first embodiment, a method of fixing the main body 3 1 of the thermistor (temperature sensitive portion) 30 to the mounting grooves 1 1 8 and 1 1 1 with the cover 1 4 is adopted.

[0037] However, when a tensile load that pulls out the main body 3 1 from the crossover wire 40 (see Fig. 6) is applied to the conductive wire 3 2, the end face 4 3 of the main body 3 1 is attached to the mounting grooves 1 1, 1 1 The end face ^ 1 1 is pulled until it comes into contact with the pit and a gap is created between the main body 3 1 and the crossover wire 40, which may make it difficult to accurately estimate the motor coil temperature.

Therefore, in Example 2, the cause of the gap, that is, the generation of a gap between the main body 31 and the crossover 40, was prevented. Specifically, as shown in Fig. 8, the formation positions of the bulging portions 1 2 and 1 2 are set to the mounting grooves 1 1 and 1 1 1

1 1 Moved to the 3 side. Here, the bulges 1 2 8 and 1 2 are the bottom 1

It is formed at the position corresponding to 1 1 and 3, and the end face of the mounting grooves 1 1 and 1 1 of the conductor 3 2 side (the side opposite to the crossover 40) 1 1 side, 1 1 side of main body 3 1 side It is formed on the crossover line 40 side. \¥0 2020/175349 9 卩 (: 171? 2020 /006973

According to this configuration, when the above-mentioned tensile load is applied to the conductive wire 32, the end face 4 3 of the main body 3 1 collides with the bulged parts 1 2 8 and 12 and the conductive wire 3 2 of the main body 3 1 The pulling to the side is restricted. Therefore, the main body 3 1 is not pulled until the contact between the double-sided surfaces 4 3 1 1 8 and 1 1 1, and the gap is eliminated and the motor coil temperature can be accurately estimated. In the second embodiment, as in the first embodiment, the cover 1 4 is used to fix the main body 3 1 to the mounting grooves 1 1 8 and 1 1 1.

[0040] Example 3>

Finally, Example 3 will be described with reference to FIG. In the third embodiment, the body 31 of the thermistor 30 is prevented from coming off.

[0041] In the first embodiment, as shown in Fig. 2, a large gap 31 is formed between the cover 14 and the upper end portion 44 of the opening of the mounting grooves 118, 11. Therefore, if a tensile load that exceeds the pressing force due to the spring force of the leaf spring 15 is applied to the conductor 3 2 during assembly, the body 3 1 may come off.In Example 3, we propose a structure that makes it difficult for the body 3 1 to come off. To do.

[0042] Specifically, the resin mold part 10 includes both sides of the mounting grooves 1 1 and 1 1 1 (upper end portion of the opening of the mounting grooves 1 1 and 1 1 1) 4 4 and a resin-made built-up part 4 4. 5 is integrally molded. The build-up portion 45 is erected between the cover 14 and the conductor wire 3 2 in a substantially rectangular shape in the vertical cross section, and the gap 3 2 between the both 1 4 3 2 is narrower than the gap 3 1.

[0043] Therefore, even if a tensile load exceeding the pressing force of the leaf spring 15 is generated on the conducting wire 32 during assembly, it is interfered by the built-up portion 45 and the main body 3 1 becomes difficult to come off. As a result, it is not necessary to assemble the thermistor 30 while taking it into consideration, and the efficiency of assembly is improved. In addition, as in Example 2, the formation positions of the bulging portions 1 2 8 and 1 2 were set to the mounting grooves 1 1 and 1 1 1

1 1 It may be configured to move to the ₃ side.
